Clinometer: A clinometer or inclinometer is an instrument for measuring angles of slope (or tilt), elevation or depression of an object with respect to gravity. It is also known as a tilt indicator, tilt sensor, tilt meter, slope alert, slope gauge, gradient meter, gradiometer, level gauge, level meter, declinometer, and pitch & roll indicator. Clinometers measure both inclines (positive slopes, as seen by an observer looking upwards) and declines (negative slopes, as seen by an observer looking downward) using three different units of measure: degrees, percent, and topo (see Grade (slope) for details). Astrolabes are inclinometers that were used for navigation and locating astronomical objects from ancient times to the Renaissance. A tilt sensor can measure the tilting in often two axes of a reference plane in two axes. In contrast, a full motion would use at least three axes and often additional sensors. One way to measure tilt angle with reference to the earth's groun

Ghat Tracer: Ghat tracer is a survey  instrument used to fix required angle in the slope sides with basic task and strategies. This basic instrument is broadly utilized for finding various focuses on the ground with fixed gradient amid preparatory course surveys.It is additionally utilized for estimating levels or angles of slopes. The instrument basically comprises of a long circular tube suspended in a straight bar by an "A" formed an edge having an eye hole toward one side and a crosshair on the other end. With a reasonable rack and pinion course of action an overwhelming weight slides along the tube. The weight at its top contains a slanted edge which slides along the graduations of the calibrated scale connected to the tube and serves as an index. The line of sight will be horizontal when the scale reads zero. The weight is slid towards the observer for ascending gradient and far from the spectator for diving inclination. The Ghat tracer survey was begun from

Hand Level: Hand Levels can be an awesome device for use by experts and customers. They are an extremely reasonable and minimal effort apparatus with a wide variety of uses. They were first made when somebody thought of joining a soul level to a telescope. Once the instrument is level, the client looks through the telescope to think about various focuses on a similar reference point. It is utilized for unpleasant leveling and not intended for accuracy work. Some of the time Professional Land Surveyors or Grading Contractors will utilize a Hand Level to get a thought or estimation of level as opposed to setting aside the opportunity to set up a tripod with a leveling instrument.Inside stadia markings help the client in deciding the separations. Land Surveyors and Land Development Professionals utilize Hand Levels and Sight Levels as they are perfect for preparatory study and straightforward separation estimation. Hand levels are perfect for laying gardens, paving, block laying

Planimeter types and digital planimeter: A planimeter, also known as a platometer, is a measuring instrument used to determine the area of an arbitrary two-dimensional shape. There are several kinds of planimeters, but all operate in a similar way. There are Three types of planimeters available however all operate in a similar way. They are: 1.Prytz hatchet planimeter, 2.linear rolling planimeter 3.Amsler (polar) planimeter and compensating planimeter.  The Swiss mathematician Jakob Amsler-Laffon built the first modern planimeter in 1854, the concept having been pioneered by Johann Martin Hermann in 1814. Many developments followed Amsler's famous planimeter, including electronic versions. The first planimeter (Prytz) is incredibly simple, but it provides only approximation of the total area. The other two of the planimeters are based on Green's theorem which relates line integral of second kind with double integral (the vector field and the domains of integratio

Dumpy level And Tripod Stand: A dumpy level, builder's auto level , leveling instrument, or automatic level is an optical instrument used to establish or verify points in the same horizontal plane. It is used in surveying and building with a vertical staff to measure height differences and to transfer, measure and set heights. Tripod Stand: A surveyor's tripod is a device used to support any one of a number of surveying instruments, such as theodolites, total stations, levels or transits. Uses of dumpy level: The dumpy level is mainly used in surveying for the following purposes: To determine relative height and distance among different locations of a surveying land. To determine relative distance among different locations of a surveying land. Invention: In 1832, English civil engineer William Gravatt, who had worked with Marc Isambard Brunel and his son Isambard on the Thames Tunnel, was commissioned by Mr. H.R. Palmer to examine a scheme for the South Easte

Mobile mapping: Mobile map ping is the process of collecting geospatial data from a mobile vehicle,typically fitted with a range of photographic, radar, laser, LiDAR or any number of remote sensing systems. Such systems are composed of an integrated array of time synchronised navigation sensors and imaging sensors mounted on a mobile platform.The primary output from such systems include GIS data, digital maps, and georeferenced images and video. History: The development of direct reading georeferencing technologies opened the way for mobile mapping systems. GPS and Inertial Navigation Systems, have allowed rapid and accurate determination of position and attitude of remote sensing equipment,effectively leading to direct mapping of features of interest without the need for complex post-processing of observed data. Applications: Aerial mobile mapping Traditional techniques of geo-referencing aerial photography, ground profiling radar, or Lidar are prohibitively expensive,

DGPS: Differential Global Positioning System (DGPS) is an enhancement to Global Positioning System which provides improved location accuracy, from the 15-meter nominal GPS accuracy to about 10 cm in case of the best implementations. DGPS uses a network of fixed ground-based reference stations to broadcast the difference between the positions indicated by the GPS satellite systems and the known fixed positions. These stations broadcast the difference between the measured satellite pseudoranges and actual (internally computed). pseudoranges, and receiver stations may correct their pseudoranges by the same amount. The digital correction signal is typically broadcast locally over ground-based transmitters of shorter range. The term refers to a general technique of augmentation. The United States Coast Guard (USCG) and Canadian Coast Guard (CCG) each run such systems in the U.S. and Canada on the longwave radio frequencies between 285 kHz and 325 kHz near major waterways and harb

Universal testing machine(UTM): A u niversal testing machine (UTM) , also known as a universal tester, materials testing machine or materials test frame, is used to test the tensile strength and compressive strength of materials. An earlier name for a tensile testing machine is a tensometer. The "universal" part of the name reflects that it can perform many standard tensile and compression tests on materials, components, and structures (in other words, that it is versatile). Universal Testing Machine is designed for testing materials and other materials under tension, compression bending, transverse and shear loads.

consolidation appartus and its types: consolidation of clay deposit prompts trouble in structures, for example, splits and disappointments. Consolidation is reduction of volume of soil because of ejection of water from its pore space caused by supported stacking. This wonder is time subordinate. The one dimensional consolidation test performed on an undisturbed example of dirt is helpful for understanding the historical backdrop of the dirt store. The test outcomes can be utilized for ascertaining the settlement of structures based on clayey soil. consolidation test is uni-dimensional test considered critical in soil mechanics. Test taken from contiguous territories of a solitary site indicate differential settlement notwithstanding when tried utilizing same methods. Soil of comparable quality may demonstrate shifting combination. Tests are painstakingly arranged and vertical settlement of the example in soaked or depleted conditions deliberately recorded when known load is connec
